Cryotherapy, which literally means “cold therapy,” is a technique where the body is exposed to extremely cold temperatures for several minutes.
The theory for whole-body cryotherapy (WBC) is that by immersing the body in extremely cold air for several minutes, you could receive a number of health benefits. The individual will stand in an enclosed chamber or a small enclosure that surrounds their body but has an opening for their head at the top. The enclosure will drop to between negative 200–300°F. They’ll stay in the ultra-low temperature air for between two and four minutes.
